<h3>Key bindings</h3>


<p>The association between a command and the key combinations that should
invoke the command is called a <b>key binding</b>.&nbsp; Plug-ins can define key
bindings along with commands in the <b><a href="../reference/extension-points/org_eclipse_ui_bindings.html">org.eclipse.ui.bindings</a></b>
extension point.</p>


<pre>...
      &lt;key <b>commandId="org.eclipse.ui.file.save"</b>
            contextId="org.eclipse.ui.contexts.window"
            schemeId="org.eclipse.ui.examples.contributions.scheme"
            <b>sequence="CTRL+S"</b>&gt;
      &lt;/key&gt;
...</pre>


<p>There is our friend <b>org.eclipse.ui.file.save</b>.  In Eclipse, the workbench registers
the <b>SaveAction</b> as a handler for this command id in every Workbench Window.</p>

<p>The <b>sequence</b> attribute for a key binding defines the key
combination that is used to invoke a command.&nbsp; When the
workbench <b>SaveAction</b> is active, the key combination <kbd>CTRL+S</kbd> will invoke it,
since the workbench uses the same command id for its <b>SaveAction</b>.</p>
